Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The utility model provides Figure 1-3The wing nut shown includes a threaded sleeve 1, the outer wall of the threaded sleeve 1 is slidably clamped with a connecting sleeve 2, the outer wall of the connecting sleeve 2 is symmetrically fixedly connected with a wing-shaped handle 3, and a locking assembly 4 is symmetrically arranged inside the threaded sleeve 1. The locking assembly 4 includes a locking block 41 and a connecting block 43. The locking block 41 and the connecting block 43 are arranged inside the threaded sleeve 1. The locking block 41 is used to lock the components connected to the threaded sleeve 1. A first limit spring 44 and a second limit spring 45 are arranged between the locking block 41 and the connecting block 43. They are used to limit the position of the locking block 41 and the connecting block 43. Under the action of the first limit spring 44, the locking block 41 can squeeze and clamp the components connected to the threaded sleeve 1 to lock the threaded sleeve 1, so as to lock the threaded sleeve 1, thereby ensuring its stability during use, and the connecting sleeve 2 can drive the wing-shaped handle 3 to separate from the threaded sleeve 1, thereby preventing the threaded sleeve 1 from loosening when the wing-shaped handle 3 is collided.
[0022] Furthermore, the outer wall of the threaded sleeve 1 is symmetrically fixed with multiple arc blocks 5, and the bottom of the inner wall of the connecting sleeve 2 is symmetrically provided with multiple sliding grooves. The outer wall of the arc block 5 is slidably engaged with the inner cavity of the sliding groove. The arc block 5 can make the connecting sleeve 2 and the threaded sleeve 1 rotate synchronously, and the arc blocks 5 on the threaded sleeve 1 are symmetrically arranged, so that when the connecting sleeve 2 and the threaded sleeve 1 are docked, the second magnet 49 on the connecting sleeve 2 can correspond to the first magnet 48.
[0023] Furthermore, the inner wall of the threaded sleeve 1 is symmetrically provided with mounting holes 42, and the locking block 41 and the connecting block 43 are slidably sleeved in the inner cavity of the mounting hole 42. The locking block 41 is provided with a tooth groove on the side away from the connecting block 43. The tooth groove on the locking block 41 can improve the stability of the locking block 41 in locking the internal connecting parts of the threaded sleeve 1.
[0024] Furthermore, a fixing plate 46 is fixedly connected to the inside of the mounting hole 42, and a plurality of fixing rods 47 are fixedly connected between the locking block 41 and the connecting block 43.
